The conversion of monosaccharides in orange peel hydrolysates to ethanol by recombinant Escherichia coli KO11 has been investigated in pH-controlled batch fermentations at 32 and 37 degrees C. pH values and concentration of peel hydrolysate were varied to determine approximate optimal conditions and limitations of these fermentations. Very high yields of ethanol were achieved by this microorganism at reasonable ethanol concentrations (28-48 g/L). The pH range between 5.8 and 6.2 appears to be optimal. The microorganism can convert all major monosaccharides in orange peel hydrolysates to ethanol and to smaller amounts of acetic and lactic acids. Acetic acid is coproduced in equimolar amounts with ethanol by catabolism of salts of galacturonic acid.

little or no steatosis in 24 of 26 (92%) PBC patients. Multive-were from biopsies from the liver pathology reference files of The sicular stellate cells were not seen in female patients with Toronto Hospital. 11 Of the 26 patients with PBC, 16 had been renormal liver histology. These results suggest that there is an corded as having duct lesions and fibrosis without cirrhosis and 10 alteration in hepatic lipid storage that involves stellate cells had cirrhosis. 11 Tissue for TEM examination had been fixed in in PBC that could be an early manifestation of this disease. universal fixative (2% glutaraldehyde and 4% formaldehyde) and processed in a standard way. Numbers of stellate cells were counted
